APPARA1US non MAKING'ME1ALLIC VEHICLE WHELS.

T0 aZZ whom z't-may concemz:

Be 1t known that we, HARRY V. Ixnmnn and ALBERT T. KELLER, c1t1zens etthe United States, and residents of Pittsburgh and Bethlehem, inthecouhties 0f Allegheny and N orthamPton, respectively, in the State ofPennsylvania, have im7ented certain new and ,nsef'ul Improvements inApparatns for l\laking Metallic Vehicle VVheels,-of which the followingis a specification. Out present invention relates to, improved apparacusfor molding metallic vehi cle wheels, and the invention aims to provideapparatus by the means of Which. a metallic Wheel having integral hollowhb, spoke and felly members may be ec0nomically and expeditionsly1i1annfactled withont reqniring l-he use. f desttrnCtible C0l'tS; suchas sand cots, fol example: A

Oui invention wi]l,be explained by aid of the accmnpanying drawings, inwhich 1-- Figure 1. is a trzjtnsverse sectional view through a moldingapparatus constructed in accordance with ourinvencion. Fig. 2 is asection online 220f Fig. 1. Fig}. is a transverse sectional view of thecompleted wheel, and

Fig. 4 is aplan view of the wheel;

, Rerring by reference characters to these drawings, we Will firstdescribe the wheel Which oui apparats is designed to produce and,whichisshown in Figs. 8 and 4. This is shown as comprisinga hub 1,:spokes 2 anda felly 3, all f01med bycasting into a single integral structure. Thespokes 2 are formed hollow as shown, and the botes of these spokes arecontinned"throngh the hnb member 1, thns imparting lightnesS andaVoidingi the use of unnecessary metal.

The felly isalso.made hollow, being specifically 0f channel shape withthe outer peripheral ed;cs of the side walls of the channel providedWith inwardly facing flanges, as indicated at 3 These fianges form arelatively b1oad bearing seat for the custo1nar metal tire carrying rim.'lhe apparatns for forining or casting the wheel above describedcomprises a mold such as shown in Figs. 1 and2, in which 6 and 71epresent complementary mold sections. each having a 1nold cavity, orcavitie's shaped t0 conf0rm approg imately t0 oi1e half of the Wheel tobe cast therein. Preferably the mold member 6 has an annnllr flange orpor- 4 1922. 'Sefial No. 573,206,

The parting line of the iii0ld formedby the members 6 and 7preferably coincides with the center line of thesjpokes. Located centrally Withinthe hub forming cavity of the '110ld,is a core plug 9 which form s the bore of the 11111). The mold sections6 and 7 are provided With annular rebates or giooves 6* and .7?

In order to form the felly in the shape shownwithout necessitating the use of a dstructible core, we providecollzipsible Segment-al cores.which extend between adjacent spoke cores;and whichcomprise cen- .inner edges of the flanges 3 and said shank '70number of spokes Which it is desired that being held in place by thecorrespOnding 1nold faces between which it is clamped, as shown 111Fig. 1. The m0lten metal may be supphed to the niold in any smtablemanner the hub :Eor1ning cavity. After the Wheel has been caSt bysnpplying the mold Wlth' n as for instance, by providing the 1nold Witha neck 7 within Which is provided a refractory lining '11, the centralbore 01' passage of which connectS by branch ports 11 with V Cal in anydesirable manner, the spoke cores may be readily withdrawn, and nponseparating the mold members the felly f0rlningcores may be readilywithdrawn by first removing the central cors sections 10 whereafter thesections 10" may be individually withdrawn,

it being understood that the fiange or enlarged portions a 01' thesections are of such size as to permit their passage through the spacebetWeen the intnrned flanges 3 of the felly.

By the use of molding ap aratus such as above described, we are enab edt0 construct a one-piecc wheel, having hollow hub, spoke and channelshaped felly members without the use of any sand cores or ocres of anature which must be destroyed in order to remove them from the 1nold.Such a wheel may be made of approxinmtely the same dimensions as thewooden wheels cnstomarily used on 1notor veliicles and can be fitted outwith the saine attachments, such as hnb centers, de- 1nonntable rnns.brake dru1ns and the like.

The mold and core parts hereinbef0re described, wonld of course, beconstructed of a snitable material, adapted to permanently retain itsorm so as to be capable of re-nse for an indefinite period, snch forexample, as a metal adapted for the purpose.

The webs or side walls of the felly channel are provided with cross lngsor webs 3 atthe points where the bolt hol'es 6 are forn1ed to receivethe usual demountable ri1n bolts. and intermediace bracing. wcbS 3 ma.yalso be provided. these Webs being formed by correspondingly recessedportions (2 and c in the arc shapcd forming portion a.

Having tlms described onr invention, what we clain1 is l. Apparatus forcasting metal wheels having channcl shziped fellies with inwardly tnrnedfianges comprising complementary mold msmbe1shaving 1nating halo, spokeand felly forming cavities, and collapsible sectional cores cooperacingwitl1 said cavities.

2. Apparatus for castng metal wheels having channel shaped fellies Withinwardly turned flanges con1prising co1imlen1entary mold members having1nating hub. spoke and felly i'orn1ing cavities, and collapsiblesectional cores cooperating withsaid cavities, said cores comprisingcentral ring members, and side ring members having oppositely extendingannular ribs.
